For short trips, American and Canadian citizens are visa-exempt for the United Kingdom, which means you can skip the visa centre appointment and the visitor visa fee.
What every US and Canadian traveler does need, since January 8, 2025, is a UK ETA, the electronic visa for the UK, also called a UK visa waiver or UK travel visa. The good news: it's quick, fully online, and approved within hours.
The UK ETA is required for:
• Tourism
• Business
• Short Study
• Transit Through Britain
